Resumo
With the objective to investigate a possible association between foot diseases, clinical mastitis
and/or metritis and predisposing factors for foot diseases, 5300 dairy cows from 80 intensive and
semi-intensive farms were used. In 325 (6.13%) cows only foot disease was diagnosed, in 35 (0.66%)
foot disease and clinical mastitis, in 52 (0.98%) foot disease and metritis, in 28 (0.53%) foot disease,
clinical mastitis and metritis, in 128 (2.42%) only metritis, in 165 (3.11%) only clinical mastitis, and in
89 (1.68%) cows metritis and clinical mastitis. Rapid changes in the diet, high exposure time of hoof
horn to slurry and wet conditions, concrete floors, use of footbaths, low frequency of claw trimming,
irregular quarantine, and no attention to health aspects during acquisition of the animals were
considered as major risk factors for the occurrence of those diseases. The McNemar test for
dependent samples showed significant statistical differences between the occurrence of foot disease,
clinical mastitis and metritis, in spite of the poor association between those diseases. It was concluded
that there was no expressive relationship between foot diseases, clinical mastitis and metritis in
lactent cows.
